2 Claims.

f' t An Yobject of this invention is to provide a ,razor so constructedras to guide the skin to be shaved in a novel manner into angularadvancement with respect to the cutting edge of the blade iby firstVretarding and then releasing the skin,

tov eifecta smooth action in shaving.

A further object-of the invention is to provide a razor so designed thatthe lower end thereof may be held in substantially vertical position forconvenience of the user; while the blade edge and skin control barthereof arer presented at an acute angle thereto, the surface to beshaved being advanced to the cutting edge of the blade in a safe andefiicient manner.

Another object of this invention is to provide smoother, cleanershavethan may be obtained 'by using razors of standard construction.

The accompanying drawingsl illustrate Y embodiments of structuresemploying my invention described in detailV in the ensuingspecification. These embodiments are merely by way of example and theinventionV is not limited-thereto vbut includes all other forms whichwould corne Vwithinthe scope of the appended claims.

V`Inthe drawings:

Fig. 1 is a fragmentary, enlarged, medially sectional view taken on lineyI--I of Fig. 3, end Vparts being shown in dotted lines,

handle having a lower end Ill, and an angularly diverted upper endportion I i disposed at an angle of 25 degrees to the lower end Iiioiethe handle as willappear in Fig. 2 iroin'angle line I2. The upper endII of the handle is provided with a widened head I3 having a blade guardor skin control bar I4 connected thereto by the end pieces I5 associatedwith the head I3. The space between Athe control bar I4 and the head I3de-` lines Yan aperture I6 for discharging lather and the debris ofshaving from the scene of the shaving operation. A blade clamp Ilextends over the top of the head I3 and along the upper end I I of thehandle where it is secured in suitable fashion I8 to the upper end II.The free end I9 of the blade clamp is bent and abuts on the blade 25.The top of the head I3 defines a seat 2| for the blade 20. Blade stops22 are secured to or formed integral with the longitudinal ends of theskin a razor which assures theV obtaining cf a thereof, teken Y controlbar I4 andv project thereabove and substantially above the plane oftheseat 2I to form stops against which the blade is positioned wheninserted in the razor. These stops 22 maintain the edge Y34 of the bladein proper spatial relationship to the guard bar or skin control bar I 4whereby the tangent line 23, which represents the face, when in shavingrelationship to the blade 2!! is disposed at an angle of 32 degreestothe seat 2| and the blade 2i?. This insures the proper incidence ofthe hairs of the beard with the edge 34 of the blade. Collectively, thehead I3, the seat 2I, the blade clamp Il are herein referred to as theblade holder.

The highest point 24 on the bar I4 is preferably approximately .028 ofan inch below the plane'of the blade at its cutting edge. This distanceis found to permita suitable angular approach'of the skin. Immediatelyadjacent the aperture I6, the bar I4 falls away from the line 2'Imarking theV high point 24, forming a trailing surface 25. In theopposite direction, proceeding from the line 21, an approach leadingsurface 26 is at and preferablyapproximately 15 degrees from tangentline 23. The curved line 28, which is the sharply dened upper edge ofthe arcuate yundercut portion 30, forms an edge that fric- .tionallyengages the skin and effects a controlled release of the skin during theshaving process.

Likewise, it acts as a guard against cutting the face by the bladebecause of an improper angular approach. It is to be noted that theapproach i leading surface 26 and the trailing surface 25 are :uniformthroughout in vertical cross-sections.

In contra-distinction, the undercut portion 30 is longitudinallyarcuate, the apex of the arc being Von line I-I of Fig. 3. The apex ofthe arch 3l is on the line I`I in Fig. 3. From the apex 3l, the archextends longitudinally in both directions to the end points 32.

In using therazor, the approach leading surface 26 will provide uniformfrictional engage- .rnent oi the skin over its entire area. However,

friction ofthe sharply deiined upper edge 28 of the arcuate undercutcauses the skin to accuin endwise sweeping motions. The approach leadingsurface 26 slows up the movement of the skin thereover, to prevent thetoo rapid presentation of the skin to the cutting edge of the blade.

In actual tests of the razor of the instant invention, drawn over a linemarked on the skin, in a direction perpendicular to that line, the lineis first observed released at the ends 32 of the undercut controlsurface 30; thereafter the center of the line is observed released atthe apex 3l oi' the undercut control surface. Thus, it appears that theedge 23 of the undercut control surface retards the skin to a greaterdegree at the center than at the ends of the undercut control surface30, releasing the skin rst at the ends 32 to define the endwise sweepingmotion above described.

The high point 24 is disposed at a tangent point to the line 23, theundercut portion 30 being substantially below the high point- Theapproach plane 25 is comparatively flatand of adequate area, providingthe friction to assure safety and a controlled skin release.

The bend I9 in the clamp breaks the continuity of contact of skin toblade as well as reduces the surface area of contact plane of clamp andchanges its angle. The bent edge I9 of the clamp impinges the blade 2Uat a point, distant B from the edge 34 of the blade, as

shown in Fig. l, approximately twice the distance A between the highpoint 2li and said edge 34. This spacing of the parts results in thesmoother presentation of the skin to the cutting edge of the blade andprevents chattering which would occur if the spacing of the parts werevaried from that just noted.

fn the structure of the instant application, the razor head and thepoints and surfaces which contact the face are so arranged in relationto the handle that the cutting edge of the blade is safely effectiveover a wider arc or range than is presently available in any otherrazor.

While I have shown in the drawings and described in the abovespecification, a convenient form of a structure embodying my invention,it will be apparent from such disclosure that the invention is capableof many modifications without departing from the spirit and scopethereof, as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A razor comprising a handle, a head on said handle having a mainportion including a fiat surface for receiving a blade having a cuttingedge, a bar spaced from said main portion of the head, membersconnecting the ends of said bar to the main portion to dispose the barbelow the plane of and spaced from the said blade-receiving surface,said members having stop portions against which the cutting edge of theblade may abut to dispose the cutting edge above the plane of the barspaced therefrom and parallel thereto, the bar in cross-section at aplane taken at right angles to the iongitudinaal axis thereof defining aflat upper portion disposed substantially 133 4 l degrees to the planeof the blade-receiving surface of the main portion of the head, a lowerundercut portion and a trailing surface connecting the top of the upperportion and bottom of the lower portion of the bar and defining the backof said bar, the said lower portion of the bar being of the outline of.an arc longitudinally, the apex of said arc being disposed immediatelyadjacent the flat upper' portion of the bar and defining a controlsurface so that in movement of the razor on a skin surface, the skinwill be first contacted by the said lower portion, and, by virtue of thearcuate outline thereof longitudinally, will be retarded most at theapex and least at the ends of the arc and will be released in continuedmovement of the razor, first at the ends of the said lower portion andthen gradually up to the apex thereof, providing an angular presentationof the skin to the blade edge for a slicing shaving action.

2. A razor comprising a handle, a head on said handle having a mainportion including a flat surface for receiving a blade having a cuttingedge, a bar spaced from the main portion of the head, members connectingthe ends of said bar to the main portion to dispose the bar below theplane of and spaced from the said blade-receiving surface, said membershaving stop portions against which the cutting edge of the blade mayabut to dispose the cutting edge above the plane of the bar spacedtherefrom and parallel thereto, the bar in cross-section at a planetaken at right angles to the longitudinal axis thereof defining a natupper portion disposed substantially 15 from an imaginary line drawnfrom the blade edge to the top of the flat upper portion, a lowerundercut portion and a trailing surface connecting the top of the upperportion and bottom of the lower portion of the bar, and defining theback of said bar, the lower portion of the front of the bar being ofarcuate outline longitudinally and defining a control surface so that inmovement of the razor on a skin surface, the skin will be rst contactedby the said lower portion and, by virtue of the arcuate outline thereoflongitudinally, will be retarded most at the apex and least at the endsof the arc and will be released in continued movement of the razor firstat the ends of the said lower portion and then gradually up to the apexthereof, providing an angular presentation of the skin to the blade edgefor a slicing shaving action.
